HORSE HAY-RAKE.

No. 848,532. Specification of Letters Patent. Patented March 26, 1907.

. nlication filed April 12,1906- Serial No. 311,311.

To all whom it may concern:

Be it known that I, EATON DAWSON BOND, a citizen of the United States,residing at Mercer, in the county of Madison and State of Tennessee,have invented a new and useful Horse Hay-Rake, of which the following isa specification.

This invention relates to horse-rakes, and has for its object to provideimproved means for automatically effecting the dumping of the rake atpredetermined intervals.

A further object of the invention is vide means operable independentlyautomatic means for manually dumping the rake and means for locking therake in lowered or operative position.

A further object is to provide a plurality of longitudinal slide-barsadapted to engage tappets on the traction-wheels to effect the dumpingof the rake, said bars being pro-. vided with trips adapted to engageand release the locking mechanism when the b ars are moved to operativeposition.

A further object is to provide an extensible axle having a sectionalrake-head secured thereto and foldable in the direction of the length ofthe rake.

A still further object of the invention is to generally improve thisclass of devices, so as to increase their utility, durability, andefiiciency.

T/Vith these and other objects in view the invention consists in theconstruction and novel combination and arrangement of parts hereinafterfully described, and illustrated in the accompanying drawings, it beingunderstood that various changes in form, proportions, and minor detailsof construction may be resorted to within the scope of the appendedclaims.

In the accompanying drawings, forming a part of this specification,Figure 1 is a perspective view of a horse-rake constructed in accordancewith my invention. .Fig. 2 is a Similar numerals of reference indicatecorresponding parts in all of the figures of the drawings.

The improved device comprises an extensible axle, preferably formed ofangle-iron, as shown, and comprising a relatively stationaryintermediate section 5 and movable end sections or stub-axles 6,provided with terminal spindles 7, upon which are journaled thetraction-wheels 8. The movable sections 6 are slidably mounted inguiding-clips 9 and are provided with offset portions forminginclinedshoulders 10, adapted to engage the adjacent ends of thestationary sections 5.

Pivotally mounted for swinging movement in the clips 9 are earns 11,adapted to engage the thickened portion 12 of the movable section forlocking the shoulders 10 in engagement with the ends of the stationarysection, there being lugs 13 extended laterally from the sections 6 andadapted to engage the clips 9 for limiting the sliding movement of saidsections. It will thus be seen that by adjusting the movable sectionslongitudinally of the intermediate sections 6 the length. of the axlemay be varied at will, the movable sections being locked in adjustedposition by actuating the cam 11, as will be readily understood.

Pivotally mounted for rotation in suitable bearing-brackets 14'is arake-head provided with depending downwardly-curved teeth 15, saidrake-he ad being formed in a plurality of sections, the end sections 16of which are pivotally' connected to the intermediate section 17 bymeans of pins or bolts 18. By having the rake-head formed in sections,as shown, the terminal sections 16 may be readily folded laterally onthe intermediate section when the extensible axle is adjusted, thuspermitting the rake to pass between gate-posts or other obstructionswithout danger of contact with the same.

Extending from the axle are lateral supto proof the transverse sectionalview showing the teeth ports 19, provided with terminal loops 20, of therake-head in elevated position. 3 and engaging said loops are connectingbars is a plan view of a portion of the rake. Fig. A or rods 21. Theconnecting bar 21 is is a similar view showing one of the pivotedrake-sections in folded position. Fig. 5 is a side elevation, partly insection, of one end of the extensible axle. Fig. 6 is a transversesectional view of one end of the axle, showing the construction of thesupporting-clip. Fig. 7 is an enlarged detail perspective view of aportion of the rake. Fig. 8 is a perspective view of a portion of one ofthe stub-axles.

formed with a terminal hook adapted to detachably engage the eye in theadjacent supporting-bar 19, whereby said connectingbar may be readilyremoved when it is desired to fold the movable sections Of therake-head.

Secured to the opposite ends of the extensible axle aresupporting-clips, each preferably formed of a single piece of wire orother material having one end thereof bent to form a terminal loop orbearing 22 for the reception of the reduced end of the adjacent foldablerake-sections, while the opposite end of the wire is bent to form a pairof spaced loops 23 and 24, disposed at the front of the axle, as shown.The reduced ends of the movable rake-sections are held in the loop orbearings 22 by means of pivoted links 25 and locking-pins 26, therebeing similar locking-links 27 engaging the loops 23 and 24, as shown.

Mounted for longitudinal movement at the front of th extensible axle areslide-bars 28, each having one end thereof bent upwardly and rearwardlyto form a yoke 29, the free end of which is provided with a ter minaleye 30, connected, through the medium of a link 31, with theintermediate section of the rake-head. The slide-bars 28 are eachpreferably formed in two sections, pivotally united at 32, the outersection of each bar being provided with a terminal angularlydisposedextension or crank 33, adapted to engage suitable tappets or bolts 34,secured to e hub or spokes of the traction-wheels, as shown, so that thetappets 34 will engage and partially rotate the slide-bars, and, throughthe medium of the yoke 29 and connecting-link 31, raise the rake-head toelevated or operative position, and thereby dump the load, as will bemore fully explained hereinafter. The yoke 29 is provided with a loop36, through which extends a guide-bar 37, the latter being pivotallyconnected at 38 to a diagonal brace 39, which connects the tongue 40with the axle, as shown.

The guide-bars 37 are one on each side of the tongue 40 and are eachconnected to one leg of the bell-crank levers 41, the opposite legs ofwhich are connected, through the medium of rods 42, with a connectin-yoke 43, disposed beneath a foot-operated lever 44, there being acoiled spring interposed between the arms of the bell-crank levers fornormally holding the slide-bars in retracted or inoperative position. Itwill thus be seen that by depressing the foot-levers 44 the bell-cranklevers will be tilted on their pivotal axes, and thus move the yokes 29and slide-bars 28 longitudinally of the axle, so that the terminalcranks 33 of said bars will extend in the path of movement of the bolts34, and in which position they will be partially rotated to effect thedumping of the rake, as before stated. The hooked ends or cranks of theslide-bars 28 engage the loops 23 of the supporting-clips and are lockedin said loops by links 23 and locking-pins 46, as best shown in Fig. 6of the drawings.

Pivotally mounted in eyes or loops 38 are braces 46, adapted to engagethe loops 24 when the axle is extended, and thus assist in 1 preferablydisposed strengthening and reinforcing the same. Pivoted to the bottomof the stationary section of the axle is a locking member 47, one end ofwhich is provided with a terminal hook 48, adapted to engage a lug orprojection 49 on the rake-head and lock the latter in lower or operativeposition, while the opposite end of said locking member projectsupwardly at the front of the axle and is disposed in the path ofmovement of a depending crank-arm 50, secured in any suitable manner toone of the yokes 29. be seen that the initial upward movement of therake-head will cause the crank-arm 50 to engage and depress the adjacentend of the locking member 47, thus releasing the lug 49 from engagementwith the hook 48, so as to permit the rake to move in a vertical plane,and thus effect the dumping of the hay, grass, or other materialcollected by the teeth. Secured to the axle is one end of a coil-spring51, the opposite end. of which is connected to the locking member 47 soas to normally exert an upward pull on said member and hold, the hookedend 48 thereof in elevated or operative position.

Pivotally mounted at 52 is a hand-operated lever 53, connected, throughthe medium of a link 54, with the stationary section of the rake-head,so that by operating the lever 53 the rake may be dumped independentlyof the automatic mechanism.

In order to permit the manual dumping of the rake, there is provided abar or rod 55, one end of which is operatively connected with theadjacent end of the locking member 47, while the opposite end thereof issecured to the tongue 40 at a point adjacent the seat 56, so that bydepressing the terminal footpiece 57 of the rod the locking member 47may be actuated to release the rake-head, and thus permit the latter tobe elevated by the hand-lever 5 3.

The operation of the device is as follows: Vfhen it is desired to dumpthe rake, the foot-lever 44 is depressed, which causes the slide-bars28, through the medium of the bellcrank levers 41, yokes 29, andconnecting links, to be extended longitudinally in the path of movementof the bolts or tappets 34, so that the movement of the traction-wheelswill partially rotate said bars and through the several connectionselevate the rake-head to operative position. The initial upward movementof the rake-head will release the locking-lever 47, and thus permit therakehead to move vertically to the full extent of its upward movement.As soon as the crank I arms 33 clear the tappets 34 the tension of thespring 45 will automatically withdraw the slide-bars 28, and thus permitthe rakehead to return to lowered or normal position, and in whichposition it will be locked by engagement of the lug 49 with the hook 48.

Vi hen it is desired to regulate the width of It will thus the rake, thecams 11 are moved to vertical position and the terminal sections of thestub-axles moved longitudinally until the desired adjustment iseffected, after which. the locking-cams are depressed and the hooks 21released from the eyes 20, so as to permit the end sections of therake-head to be folded rearwardly on the adjacent stationary section, asbest shown in Fig. 4 of the drawings.

From the foregoing description it is thought that the construction andoperation of the device will be readily understood by those skilled inthe art, and further description thereof is deemed unnecessary.
